1. λεξικὸν κατὰ στοιχεῖου

Photius (cod. 145) gives a brief account of his λεξικὸν κατὰ στοιχεῖου, which embraced chiefly prose words. The work is again quoted by Photius (Phot. Bibl. 158, p. 100a. 38 ed. Bekker) under the title of τῶν λέξεων συλλογή. Suidas calls it λέξεως παντοίας χρῆσις κατα στοῖχειον.

Other works

Suidas also mentions also the following works by Helladius: 2. Ἔκφρασις φιλοτιμίας. 3. Διόνυσος ἢ Μοῦσα.4. Ἔκφρασις τῶν λουτρῶν Κωνσταντιανῶν.5. Ἔπαινος Φεοδοσίου τοῦ Βασιλέως. It is likely, from the titles, that some of these works were poetical.
